ASP.NET / VB / REGEX: Convert dashes to bullets if at beginning of line

I want to replace a dash with a bullet if it is at the beginning of a line.

The problem with my code is that it does not work on the first line.  It works for all lines except the first line.

This:
- Hello world
- This is a test
- Item XYZ

Should become this:
• Hello world
• This is a test
• Item XYZ

 
input = RegularExpressions.Regex.Replace(input, VbNewLine + "- ", VbNewLine + "• ")

Its bacause you have "VbNewLine" in the expression.

Regex.Replace(input, "^- ", "• ") will get the first one.  The easiest would be to just call both.

input = RegularExpressions.Regex.Replace(input, "^- ", "• ") ;
input = RegularExpressions.Regex.Replace(input, VbNewLine + "- ", VbNewLine + "• ");

The reason why it does not work in the first line is becuase the first does not contain any carriage return or new line. Your code replaces only the character that is VbNewLine with "- ". As a work around append try the below code:

Approach one:
input = "•" + RegularExpressions.Regex.Replace(input, VbNewLine + "- ", VbNewLine + "• ")

Open in new window


Approach two:
input = string.Format("{0}{1} {2},"VbNewLine, "-", input)
input = RegularExpressions.Regex.Replace(input, VbNewLine + "- ", VbNewLine + "• ")

Typo erro, approach two should be like this:

Approach two:
input = string.Format("{0}{1} {2}"VbNewLine, "-", input)
input = RegularExpressions.Regex.Replace(input, VbNewLine + "- ", VbNewLine + "• ")
